Acknowledgements I would like to acknowledge to the following, for helping directly and indirectly with this thesis: This PhD thesis could not have been made without the help and tremendous support of my supervisor Per Roos. I will like to express my deepest gratitude for his professional guidance during my PhD study. I thank him for supporting me in finishing this work, for always helping and encouraging me to go on even if things do not go as expected, for sharing his analytical skills with me, for what he taught me about ICP-MS, for teaching me how to see the science in an attractive way. From his special, pleasant and skilled personality I have learnt things that I will carry with me all my life. In particular, I want to express my gratitude to Senior Scientist Ala Aldahan for collaboration in the late period, and response to all my scientific writing stuff. He encouraged me to go on, even when things felt a little challenging. I owe special thanks to Sven P. Nielsen, Head of Radioecology and Tracers Programme, Radiation Research Division, Risø National Laboratory for Sustainable Energy, Technical University of Denmark, for helping me always and particularly in difficult moments. Many thanks go to Susan Zumbach Johannesen, PhD Programme from DTU, for always being there when I need her, for always finding the best solutions for me and for always being so kindly. My sincere appreciations go to Jussi Jernström for spending time on discussing my questions and helping me with the HPLC-ICP-MS analysis and Kasper G. Andersson for all his constructive comments to all my scientific writing stuff. His friendly and never ending positive attitude has always encouraged me in this work. Especially thanks go to friends Sorin P. Aburel, Lars R. Lindvold and Hedi S. Pedersen for support, constructive comments to scientific writing stuff and always interesting discussions in the office/laboratory. I’d also like to thank my office/building mates Christina Ankjærgaard, Keliang Shi, Jixin Qiao, Peng He, for the nice working atmosphere. Thanks to all my colleagues from Radiation Research Division and especially to those from the Radioecology and Tracers Programme for collaboration, answers to my questions and all happy moments. Among them I will mention Liga Bech, Lise Brandt, Susanne Kjærulff, Charlotte R. Mikkelsen, Kristina W. Veirø, Yu Yixuan, Yusuf M.Abdirahman, Jytte L. Clausen, Birgitte Sindholt, Svend Olsen and Claus Bang. 8
None of this would have been possible without the love and support of my family. I thank my parents (Daniela and Marin), my uncle Marian, my beloved nephew Patrick, sisters (Elena and Natalia) and brother (Raul) and theirs families, my mother in law (Lis) for supporting and encouraging me during all those years. And finally I thank Alexander S. Hansen and Peter Hansen for sharing every up and down moment. Their support and understanding mean the entire world to me. 9
